UNITED STATES HERMAN M. WOLTER, OF SAN FRANCISCO, GALIFOBNIA..

HEADLIGHT.

Application filed December 4, 1922. Serial No. 604,853.

To all whom it may concern:

Be it known that I, HERMAN M. WOLTER, a citizen of the United States, and a resident of San Francisco, county of San Francisco, State of California, have invented a new and useful Headlight, of which the following is a specification.

The present invention relates to improvements in headlights for motor vehicles or the like, and its particular objects is to provide a very simple and convenient means for protecting the eyes of an approaching driver or pedestrian from the glare of the light. The particular featu're of the present invention is its simplicity as compared with the devices used at the present time for the same purpose.

The preferred form of the invention is illustrated in the accompanying drawing in which Figure 1 shows a front view of a headlight having my protecting feature embodied therein; Figure 2 a vertical section through the'headlight; Figure 3 a vertical section showing. a modified form of window for the headlight; Figure 4 a vertical section showing a further modification; Figures 5 and 7 vertical sections sections showing other modifications; and Figure 6 a front view of two headlights shown in their respective places on a motor vehicle and illustrating an additional feature of my invention. While I have shown only the preferred form of the invention, I wish to have it understood that various changes or modifications may be made within the scope of the claim hereto attached without departing from the spirit of the invention.

The preferred form of my invention is shown in Figures 1 and 2, the headlight (1) comprising a light housing (2), a reflector (3) mounted therein, an electric light (4) supported in the socket (6) mounted in the housing, and the window (7) disposed in front of the housing. The window which is preferably made of glass is provided with a central embossment (8) of comparatively small diameter so as to provide a cavity (9) which is preferably filled with a colored liquid, such as alcohol or the like. The position of the embossment need not necessarily becentral but should be such that it will divert and partly absorb the light rays which normally would strike the eye of the approaching driver or pedestrian.

While the embossment shown in Figure 2 is substantially semi-spherical, the one shown in Figure 5 and marked (11) is spherical in shape, and projects from both sides of the window (12). In Figure 4 is shown a conical embossment (13) projecting forwardly from the window (16). Another modification shown in Figure 5 illustrates a solid embossment (17 preferably of conical shape and made'of colored glass as distinguished from the transparent remainder (18) of the window.

Different colors may be selected to suit different tastes and conditions, but my vention would particularly adapt itself to a scheme for indicating to an approaching driver or pedestrian the location of each of two headlights which becomes important if one of the headlights happen to be inoperative. In the latter case it happens that collisions occur due to the fact that the driver of an approaching automobile, seeing only one light, fails to recognize wheth er it is the one on the right hand side or. on the left hand side, which causes him to misjudge the distance at which he should pass the other machine. A general rule might be adopted, for instance, that green should indicate the right hand side and red the left hand side, and the embossments in my headlights might be colored in accordance with this rule as shown in Figure 6. This would eliminate errors in judgement and would probably prevent a certain number of accidents.

While the embossment probably constitutes a valuable feature of my invention, the idea mightbe carried out without the use of an embossment as illustrated in Figure 7, in which the window (19) is shown as provided with a colored insert (21) not projecting beyond the surfaces of the window. An insert of this character or even a colored spot in the window in the right place might accomplish similar results, although probably less. effectively.

I claim:

A lens for the head-light of a motor vehicle comprising a trans arent disc having a central bulb formed integral therewith and filled with a colored liquid adapted to absorb certain constituents of the light rays passing therethrough for eliminating the glare of the headlight and for indicating to an observer the position of the headlight on the motor vehicle. i
